DOOR-LOCK.

To all whom it may concern:

Be it known that I, WILLIAM H. Mo- ZINGO, a citizen of the United States, residin the county of Knox and State of Missouri, have inventeda new and useful Door-Lock, of which the following is a specification.

The present invention appertains to looks and latches, and aims to provide a novel and improved device of that character for use upon doors and the like and c0mpr1s1ng a novel assemblage of the component elements to enhance the utility and eificiency of the lock.

Another object of the invention is the provision of a lock which can be read ly applied to a door or other object, and which can be reversed easily. I

Another object of the invention is the provision of a lock having a double lock bolt and novel means form ounting and actuating the same.

A still further object of the invention is the provision of novel means for locking and releasing the double lock bolt.

It is also the object of the invention to provide a lock of the nature indicated which is comparatively simple, compact and inexpensive in construction, and whlch 1S durable and efficacious.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that. changes in the precise embodiment of the invention herein disclosed, canbe made within the scope of what is claimed, without departing from the spirit of the invention.

The invention isillustrated in the accompanying drawing, whereinz- Figure 1 is a median section of the lock taken on the line 1-1 of Fig. 2, port1ons being shown in elevation.

I Fig. 7 is an elevation of the key used for turning the detent.

11 carrying out the invention, there is provided a pair of adjacent parallel tubular casings 1 coextensive'in length and disposed side by side, and said casings can be readily applied by drilling two bores 2 in the door or other object 3 to mortise the look within the door, and the casings can be readily reversed for reversing the look. A face plate 4 is attached to the outer or forward ends of the casings 1 which have the lugs or lips 5 extending through slots 6 inthe face plate 4 and swaged to secure the parts together. Two of the lugs 5 of the two casings extend through the same slot to hold the casings together. The apertured end portions plate 4 can be secured to the edgeof the door by means of screws 7 or other means elrllgaged through the plate 4 and taking into t e is slidable within each casing 1, and said bolts are provided at their outer or forward ends with reduced beveled portions 9 extending through openings 9 of the plate 4 to snap into engagement with the keeper (not shown) for holding the door in closed position. The bolts 8 in-seating against the plate 4 are limited in their outward movement.

In order to project the bolts, springs are provided. For t 10 are fitted within the casings 1 in rear of the b are connected by a web perspective. view of the parti-.

olts 8 and 11 extending through longitudinal slots 12 with which the adjacent portions of the casings are provided, said slots 12 extending to the rear or inner ends of the casings, in order that the disks 10 can be inserted from the rear. The disks 10 are held in place by means of rivets or pins 13 extending through the casingsl behind the disks, and coiled wire expansion springs 14 are disposed within the casings and are confined between the disks 10 and rear ends of the bolts 8 for projecting said bolts or the portions 9 thereof.

As a means for uniting the bolts 8 for simultaneous operation, a U-shaiped yoke 15 is provided, the limbs thereo projecting forwardly and sliding along the opposite sides of the casings 1 within the se. The

door. A cylindrical lock or latch bolt 8 of the i his purpose, partition disksv terminals of the yoke 15 are received by recesses 16 with which the bolts 8 are provided, and said terminals are bent at an angle, as at 17, to be embedded within the bolts 8 whereby the bolts and yoke move together, the yoke connecting the bolts so that they move as a unit. The limbs of the yoke 15 slide through notches 19 provided in the opposite edges of the disk 10, and the intermediate portion of the yoke projects through and is movable longitudinally within the slot 12, said intermediate portion being indented, as at 18.

The means for retractin the bolts or double bolt, embodies an elliptical rocker or cam 20 extending through the slot 12 with its ends projecting into the two casings, and said rocker 20 has a non-circular opening 21 between its ends through which the knob spindle 22 extends from one side of the door to the other between the casings 1 at right an les to the common plane thereof, suitab e knobs 23 being secured upon the ends of said spindle for rocking the rocker 20 in 25 either direction. The rocker is provided with a peripheral groove 25 to fit the yoke 15, which is preferably bent from a rod, and when the rocker is oscillated in either direction, one end portion thereof will engage the intermediate portion of the yoke 15 and move toward the indent 18 for forcing the yoke inwardly to retract the bolts- 8, and when the knob is released, the springs 14 will again project the bolts and return the rocker 20 to normal transverse position.

Side lates 24 are secured to the opposite sides 0 the door 3, and can serve as bearin s for the spindle 22.

11 order to lock the bolts 8 in projected position, they are provided at adjacent portions with confronting rounded notches 25, and a transverse cylmdrical detent 26 is rotatable in the adjacent portions of the casings 1 and in a transverse bore 26' with which the door is provided. The detent 26 has diametrically opposite rounded notches 27 for the passage of the bolts 8, while the notches of the bolts are adapted to receive the web of the detent between the notches 27 when the detent is turned.

In order to conveniently turn the detent from the inside, a tongue 28 has a portion 29 journaled through the inner plate 24, and the free end of the tongue is seated within a slot 30 with which the inner end. of'the detent is provided, whereby the detent turns with the tongue. A finger piece 31 is attached to the portion 29, and can be readily swung to turn the detent.

The detent 26 is held between the tongue 28 and a pin 32 projecting inwardly from the outer plate'24, the pin 32 havin a reduced portion 33 engaged through sai plate, and the free end of the pin 32 pivotally en- 65 gages the outer end of the detent 26. This will are projected and prevent the detent from shifting lon 'tudinally of itself out of place, but enab es the detent to be rotated easily. The outer end of the detent has a slot 34 for the engagement of a suitable key, such as illustrated in Fli- 7.

. disk 35 is pivoted upon the outer portion 33 of the pin 32 and has diametrically opposite radial slots 36, while the outer plate 24 has arcuate slots 37.

The key embodies a pair of levers 39 pivoted between their ends, as at 40, to a connecting piece 41, and said levers 39 have overlapping finger pieces 42 at one end, and key bits 43 at the other end. By inserting the bits 43 through the slot 36, and swinging the finger pieces 42 away from one another, the bits 43 are swung toward one another to properly engage in the slot 35 of the detent, whereby the key can be turned for turning the detent, the slots 37 limiting the turning movement of the key to either bring the detent to looking or releasin position. When the detent is' turned to tie position illustrated in Figs. 1 retracted, since they can slide through the notches 27 of the detent, but when the bolts the detent turned through substantially one quarter of a circle,-the detent will be brought within the notches 25, thereby preventing the retraction of the bolts, and thus locking them.
